In offense, a call 'Iso ______!' instructs clearing space for the named recipient. What does this mean?

• A. Interfere with the defender's positioning
• B. Isolate that player by clearing space
• C. Double-team that player
• D. Screen the cut

Answer: (B)

Iso means isolating that player by clearing space for them. When you call it, teammates vacate the area around the named receiver so they have a clean, one-on-one matchup. This gives the receiver room to make a cut, get open, and the thrower a straightforward target with less help defense in the immediate space. It’s used when a player has a favorable matchup or you want to create a quick, high-percentage opportunity downfield. It’s not about crowding or tagging the defender, it isn’t about double-teaming, and it isn’t about screening the cut—the goal is simply to clear out and let the designated player operate with space.
